Biting cold conditions – below-freezing in some areas – will sweep across a large swath of the United States Sunday while heavy, record-breaking lake-effect snow makes post-holiday travel “treacherous” and nearly “impossible” in parts of the Great Lakes region.

States braced for more whiteout conditions in the coming days as a lake-effect storm dropped several feet of snow in parts of the region by the early weekend.

The Great Lakes region will get hit with another snowstorm next week after getting blasted by a lake-effect storm this holiday weekend.
